Aim of the Hotmaps Horizon 2020 project was the development of an open-source heating and cooling mapping and planning toolbox that provides data at local and national level for EU28. The toolbox is primarily meant to help public authorities and energy planners develop heating and cooling strategies for a region, by mapping and analysing resources and energy needs. However, the same information could be utilised by an energy community investigating the potential of district heating or other solutions for heating and cooling in a large area.
The tool and related modules run without requiring any other commercial tool or software, nor registration. However, a registered user can save their session and recall it later on. Furthermore, the source code and datasets are available online, while the accompanying Wiki page offers a detailed manual, training material, examples and other guides. The data collection and calculation methods are described in detail in a project deliverable also linked in the Wiki page.
